AIM:
The main of the project to exchanging the data between two pcâ€™s using IR communication.
.
PURPOSE:
The purpose of the project is to make communication between two people each other can send their data to another one by IR communication without paying charges to sending their data to others.

Description:
In this system mainly we have two sections to exchange the data between two PC. One is at one user side and second one is at second user side .in this project data exchanging is going done by IR transmitter and receivers but at a time both canâ€™t transmit and receive the data because of half duplex communication. So while the time of user 1 section sending the data user 2 section have to receive the data. so like when the data transmitting from the second user first user has to receive the data.
Transmitting and receiving are two module are placed in each of two section .while the data transmitting time the data must be given by Pc to microcontroller and that given to encoder and then is given toward IR transmitter and while receiving data from other end first data will received by IR receiver and that will be Decoded by decoder and given to microcontrollerâ€™s input depending upon that received data by microcontroller that will be displayâ€™s in Pc.
